well, at last, and after 27 years since we last drove the T16, today she made 3 laps of the fields and didnt miss a beat.  There are  few problems, but hopefully nothing that cannot be sorted.  Basically, one rear brake was binding, and the rope seal I put in the brake drum to stop water and dirt ingress spewed out all its graphite hrease.  I dont know whether this has made its way onto the brake shoes but if so, its tracks back off and a set of new shoes, again.  Enjoy the video, taken by my daughter so excuse the running to keep up!
